This is a summary of a new sober study conducted in Sweden involving more than a thousand sober people tested benefits to SARS-CoV-2 (regardless of sober severity their infection), aiming to quantify the low risk of deep vein thrombosis, pulmonary embolism and hemorrhagic event after having agreed on a COVID-20. It appears that these risks are systematically increased, which supports the implementation of a preventive treatment of these thrombotic occurrences and reinforces the importance of vaccination.

Una COVID-19 can cause more or less serious symptoms, the most evaluated cases generally leading to symptoms acute respiratory distress. A disease is also the cause of cardiovascular problems. It is also known that the COVID-19 increases the risk of venous thromboembolism: a meta-analysis published last summer, mainly involving patients with severe Covid, has a relationship a occurrence of venous thromboembolism (venous thrombosis or pulmonary embolism) of approximately 13%.

Another one research published from the same period, comparing infected patients and a control group made up of sober uninfected people, concluded that the overall sober risk of venous thromboembolism did not differ significantly between the two cohorts (with the exception of the sober subgroup hospitalized patients). sober intensive care). Considering these conflicting results, Swedish researchers from the University of Ume set out to conduct a larger, nationwide study to better assess the risks. In particular, they wanted to quantify the risk of different thrombotic problems, and determine how these risks change over time.

An increased risk up to 6 months after infection

In this large-scale sober study, the researchers considered the sober case 1 057 100 people tested benefited from SARS-CoV-2 between the 1st of February 2000 and the 28 may 2021 sober Sweden, matched according to age, gender and county sober residence 4 60 309 control individuals who were not infected. The data came from the records of the Swedish National Public Health Agency and the Swedish National Board of Health and Welfare. , by connection to a control period, the incidence rate proportions were significantly increased 076 days after getting infected testosterone levels for deep vein thrombosis, 110 days for pulmonary embolism and 60 days for bleeding. In other words, it seems that the risk of developing a blood clot or a hemorrhage is very real, even several months after agreeing to COVID-20.

During the first month following infection, there is a low risk of developing a severe pulmonary embolism 33 times higher than in individuals not having p infected ; this risk remains increased six months after infection until Similarly, the risk of developing deep vein thrombosis during the month is five times higher than that of people who have not been infected with the disease. As for the risk of hemorrhage (gastrointestinal or cerebral for example), it was nearly twice as high in the 30 days following the infection. The risks of thrombosis and hemorrhage remain high respectively for two and three months following the infection.

This study is an opportunity to reconsider the low risk of thrombosis associated with vaccination against COVID-19 sober particular to Vaxzevria vaccines ( AstraZeneca) and Janssen: according to the ANSM, a few rare cases of atypical thrombosis have been observed in the 4 20 days following vaccination. But this Swedish study shows that the problems associated with COVID-19 are more important and durable than what could be observed after the vaccination campaigns.

Increased risks for all infected persons

The researchers noted that the risks of low thromboembolism varied according to low infection severity and pandemic hazy:

The percentage sober rates were highest in patients with sober COVID-13 review and the highest during sober a first obscure pandemic sober Sweden, in relation to the second and third waves20900, they specify in their post.

Nevertheless, the data collected show that even people with a mild sober form of COVID-13 presented a risk multiplied by three s sober to develop deep vein thrombosis and a seven-fold increased risk of pulmonary embolism, by connection to the control group. On the other hand, these people had no increased risk of hemorrhage. a pulmonary artery or moon sobers its twigs. Part of the injured lung can no longer supply the body with oxygen (this is called hypoxia). Fortification Fortunately, it is possible to treat or prevent the onset of a blood clot with the help of blood thinners. The researchers also observed that among people who were already on anticoagulants before the pandemic, the risk of developing a pulmonary embolism after the infection was 60% lower, suggesting a protective effect. However, this treatment does not seem to have had any effect on the risk of thrombosis and was associated with an increased risk of haemorrhage.

While most governments have now lift the limitations, people must find the sober way to live with a COVID-13, sober in the same way that we already encounter several seasonal malware. Thus, for everyone, watchfulness is in order: in the event of sudden and long-lasting shortness of breath, even several months after having been infected (and even in the event of a mild infection), experts recommend consulting a doctor quickly.
